膜片聯軸器在傳遞扭矩的同時通過彈性膜片的的變形來補償軸向和角向的位移，是一種高性能的金屬彈性撓性聯軸器。膜片式聯軸器結(jie)構緊湊，傳遞(di)扭矩(ju)大，使用壽命長，免(mian)維護，耐高(gao)(gao)溫，耐酸(suan)堿(jian)防腐蝕，適用于高(gao)(gao)溫高(gao)(gao)速及有腐蝕工況環境的軸系傳動。

膜片(pian)型聯(lian)軸(zhou)(zhou)器能補償主(zhu)動(dong)機(ji)與(yu)從(cong)動(dong)機(ji)之間由于制(zhi)造誤差、安裝誤差、承(cheng)載變形以及溫升變化的影響(xiang)等所(suo)引起(qi)的軸(zhou)(zhou)向、徑向和(he)角向偏移。膜片(pian)彈性(xing)聯(lian)軸(zhou)(zhou)器屬金屬彈性(xing)元件(jian)撓性(xing)聯(lian)軸(zhou)(zhou)器，其(qi)依靠金屬聯(lian)軸(zhou)(zhou)器膜片(pian)來聯(lian)接(jie)主(zhu)、從(cong)動(dong)機(ji)傳(chuan)遞扭矩，具(ju)有彈性(xing)減振、無噪聲、不需潤滑的優點。

膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)至少由一(yi)個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)和兩個(ge)(ge)軸(zhou)(zhou)(zhou)套(tao)組成(cheng)。膜(mo)片(pian)(pian)(pian)(pian)被用(yong)銷釘緊固在軸(zhou)(zhou)(zhou)套(tao)上(shang)一(yi)般不(bu)(bu)會松動或引起膜(mo)片(pian)(pian)(pian)(pian)和軸(zhou)(zhou)(zhou)套(tao)之間的(de)反(fan)沖。有(you)(you)一(yi)些生產商提供兩個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)的(de)，也有(you)(you)提供三個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)的(de)，中間有(you)(you)一(yi)個(ge)(ge)或兩個(ge)(ge)剛性元(yuan)件，兩邊(bian) 再連在軸(zhou)(zhou)(zhou)套(tao)上(shang)。單膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)和雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)的(de)不(bu)(bu)同(tong)之處是處理各種偏(pian)差能力的(de)不(bu)(bu)同(tong)，鑒(jian)于其(qi)需要膜(mo)片(pian)(pian)(pian)(pian)能復雜的(de)彎(wan)曲，所(suo)以(yi)單膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)不(bu)(bu)太適應(ying)偏(pian)心。而雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)可(ke)以(yi)同(tong)時曲向不(bu)(bu)同(tong)的(de)方向，以(yi)此來補償偏(pian)心。
